Hi i got 9cm
i replaced each block with the variable x
i set the first line of blocks equal to the second line of blocks
then solved for x
x=9
Lets get these into improper fractions.
1*8 + 5 = 8+5 = 13
13/8
1*3 + 2 = 3+2 = 5
5/3
Now divide
13/8 = 1.625
5/3 = 1.6666
1 2/3 is larger
E=egg, t=toast
2e+t=1.50
2e+3t=2.30
2t=80, toast=40
2e+40=1.50
2e=110
1egg=55
